    SUMMARY *
    Standing
    The panel reversed the district court’s dismissal for lack
    of subject matter jurisdiction of an action brought by the
    State of Arizona against federal defendants alleging that the
    American Rescue Plan Act (“ARPA”) violated the
    Constitution’s Spending Clause and the Tenth Amendment.
    Congress passed ARPA to help state, local, and tribal
    governments mitigate the ongoing effects of the COVID-19
    pandemic. The statute contains a provision (the “Offset
    Provision”) – challenged in this appeal – prohibiting a State
    from using ARPA funds to subsidize a tax cut or otherwise
    a reduction in state net tax revenue. Specifically, Arizona
    contends that it was coerced into accepting the Offset
    Provision because of the size of the funds offered under
    ARPA and the fraught financial situation brought on by the
    pandemic.      Arizona sought a preliminary injunction
    enjoining the federal defendants from recouping funds or
    otherwise enforcing the Offset Provision, and declaratory
    relief that the Offset Provision violated the Constitution.
    The district court dismissed for lack of subject matter
    jurisdiction, finding that Arizona did not demonstrate a
    cognizable injury in fact to establish standing.
    The panel held that Arizona had standing to challenge
    ARPA both because there was a realistic danger of ARPA’s
    enforcement, and because there was a justiciable challenge
    to the sovereignty of the State, which alleges infringement

    STATE OF ARIZONA V. YELLEN                     3
    on its authority to set tax policy and its interest in being free
    from coercion impacting its tax policy.
    The panel addressed Arizona’s three primary arguments
    for standing. First, Arizona under its compliance cost theory
    contended that the reporting requirements in the Treasury
    Department’s Interim Final Rule (explaining how it would
    implement ARPA and the Offset Provision) established an
    injury in fact by imposing a regulatory burden on the States.
    The panel rejected this theory because standing is measured
    at the time of the complaint, and when the complaint was
    filed, there was not a required compliance scheme.
    Second, Arizona alleged that the future injury it will
    suffer, if the Offset Provision is enforced against it, was
    sufficient to confer standing. In Susan B. Anthony List v.
    Driehaus, 
    573 U.S. 149
    , 159 (2014), the Supreme Court set
    forth three factors that must exist for a plaintiff to have
    standing to bring a pre-enforcement challenge to a law. The
    panel held that the first Driehaus factor – requiring an intent
    to do an act “arguably affected” by a constitutional interest
    – was met. In evaluating the second Driehaus factor, the
    panel determined whether Arizona’s intended future conduct
    was proscribed by ARPA. Here, Arizona accepted ARPA
    funds, certified that it will meet ARPA’s conditions, and
    passed a $1.9 billion tax cut. The panel held that Arizona’s
    tax cut would presumably lead to a reduction in Arizona’s
    net tax revenue, which meant that Arizona had taken all
    requisite steps to violate the Offset Provision short of using
    ARPA funds “directly or indirectly” to offset a net revenue
    reduction from its tax cut. This was enough to satisfy the
    second factor. The panel held that the third Driehaus factor,
    concerning whether there was a credible threat of
    enforcement, had dispositive weight in the case. The $1.9
    billion tax cut Arizona passed was a sufficiently concrete
    4              STATE OF ARIZONA V. YELLEN
    plan. The panel disagreed with the district court’s rejection
    of this theory of standing, and held that Arizona has alleged
    a sufficiently credible threat of enforcement to bring a pre-
    enforcement challenge to ARPA’s Offset Provision.
    Third, the panel examined Arizona’s sovereign injury
    theory of standing in the alternative. Arizona contended that
    the Offset Provision inflicted cognizable sovereign injuries
    upon the States by being unconstitutionally ambiguous and
    coercive. Because the panel was reviewing an order on a
    motion to dismiss, the panel took all allegations of the
    complaint as true. The panel saw no reason to dispute, deny,
    or discredit Arizona’s contention at this stage that ARPA and
    its Offset Provision specifically had a coercive impact on the
    State. Here, Arizona alleged sufficiently concrete and
    particularized harms to its ability to exercise its sovereign
    prerogatives, intangible as those prerogatives may be. The
    quasi-contractual funding offer at issue here can be
    challenged by Arizona at the outset for offering conditions
    that are unconstitutionally ambiguous or coercive. States
    have standing when an allegedly unconstitutional funding
    offer is made to them, and they do not need to first violate a
    condition of an allegedly unconstitutional contract to have
    standing to challenge it. The panel held that the district court
    erred in dismissing Arizona’s claim for lack of subject
    matter jurisdiction.
    After concluding that Arizona had standing to bring its
    challenge to ARPA on two theories, the panel declined to
    consider the merits of Arizona’s constitutional claims. The
    panel remanded for the district court to consider the merits
    of Arizona’s Spending Clause and Tenth Amendment
    claims.
    STATE OF ARIZONA V. YELLEN                   5
    Concurring, Judge R. Nelson agreed that Arizona had
    standing to challenge the Offset Provision on its theory of
    sovereign injury and concurred in Section II of the
    majority’s opinion. He disagreed with the majority’s
    conclusion that Arizona alleged “an intention to engage in a
    course of conduct arguably affected with a constitutional
    interest, but proscribed by a statute.” See Susan B. Anthony
    List, 573 U.S. at 159. Arizona never alleged that it had taken
    action proscribed by the Offset Provision, and this lack of
    such an allegation doomed Arizona’s argument for standing
    on this basis.

    OPINION
    GOULD, Circuit Judge:
    It is well established that Congress has the power
    pursuant to the Spending Clause to pass legislation
    authorizing federal grants to the States that come with strings
    attached. For the most part, cases challenging Spending
    Clause legislation come to us arising from a specific dispute
    between the federal government and the recipient of federal
    funds. Usually, the federal government will claim that the
    recipient violated a condition that Congress placed on the
    federal grant and demand repayment. The recipient, in turn,
    will claim that the condition on the funds violates the limits
    of the Spending Clause, as enumerated in South Dakota v.
    Dole, 
    483 U.S. 203
     (1987).
    This appeal, however, requires us to decide whether a
    State has standing to challenge the constitutionality of
    Spending Clause legislation before a specific and concrete
    dispute arises between grantor and grantee. We hold that
    Arizona has standing to challenge the American Rescue Plan
    Act, 
    42 U.S.C. § 802
    (c)(2)(A), (“ARPA” or “the Act”), both
    because there is a realistic danger of ARPA’s enforcement,
    and because there is a justiciable challenge to the
    sovereignty of the State, which alleges infringement on its
    authority to set tax policy and its interest in being free from
    coercion impacting its tax policy.
    8              STATE OF ARIZONA V. YELLEN
    BACKGROUND
    Congress passed the American Rescue Plan Act, Pub. L.
    No. 117-2, 
    135 Stat. 4
    , in March 2021 to help state, local,
    and tribal governments mitigate the ongoing effects of the
    COVID-19 pandemic. ARPA provides nearly $200 billion
    in new federal grants to States. 
    42 U.S.C. § 802
    (b)(3)(A).
    Arizona accepted ARPA funds and expects to receive $4.7
    billion in total aid from the Act, equivalent to about a third
    of Arizona’s total budget for the 2022 fiscal year.
    Like most federal funding, ARPA funds come with
    conditions attached. The Act delineates permissible uses for
    its funds:
    (A) to respond to the public health emergency
    with respect to the Coronavirus Disease
    2019 (COVID-19) or its negative
    economic impacts, including assistance
    to households, small businesses, and
    nonprofits, or aid to impacted industries
    such as tourism, travel, and hospitality;
    (B) to respond to workers performing
    essential work during the COVID-19
    public health emergency by providing
    premium pay to eligible workers . . . or by
    providing grants to eligible employers
    that have eligible workers who perform
    essential work;
    (C) for the provision of government services
    to the extent of the reduction in revenue
    of such State, territory, or Tribal
    government due to the COVID-19 public
    health emergency . . . ; or
    STATE OF ARIZONA V. YELLEN                  9
    (D) to make necessary investments in water,
    sewer, or broadband infrastructure.
    
    Id.
     § 802(c)(1). In addition to specifying permissible uses
    for the funds, ARPA also stipulates impermissible uses.
    First, no State or territory may use ARPA funds “for deposit
    into any pension fund.” Id. § 802(c)(2)(B). Second, the
    statute contains a provision—challenged in this appeal—
    prohibiting a State from using ARPA funds to subsidize a
    tax cut or otherwise offset a reduction in state net tax
    revenue. More specifically, this condition (hereinafter the
    “Offset Provision”) provides:
    A State or territory shall not use the funds
    provided under this section or transferred
    pursuant to section 803(c)(4) of this title to
    either directly or indirectly offset a reduction
    in the net tax revenue of such State or
    territory resulting from a change in law,
    regulation, or administrative interpretation
    during the covered period that reduces any
    tax (by providing for a reduction in a rate, a
    rebate, a deduction, a credit, or otherwise) or
    delays the imposition of any tax or tax
    increase.
    Id. § 802(c)(2)(A). If a State wants to accept federal money
    under ARPA, it must certify to the Treasury Department that
    it will use the funds “in compliance with” these conditions.
    Id. § 802(d)(1). ARPA provides that if a State violates the
    Offset Provision, it must repay the Treasury the lesser value
    of the amount of funds used in violation of the condition or
    the total amount of funds received under the Act. Id.
    § 802(e). ARPA also authorizes the Secretary of the
    Treasury to “issue such regulations as may be necessary or
    10             STATE OF ARIZONA V. YELLEN
    appropriate to carry out this section.” Id. § 802(f). It is this
    Offset Provision which is the subject of the State’s
    challenge.
    The Treasury Department issued an Interim Final Rule
    (“IFR”) in May 2021 explaining how it would implement
    ARPA and its conditions, including the Offset Provision.
    See Coronavirus State and Local Fiscal Recovery Funds, 
    86 Fed. Reg. 26,786
     (May 17, 2021) (codified at 
    31 C.F.R. § 35.1
     et seq.). Specifically, the IFR provides that a State
    will
    be considered to have used [ARPA funds] to
    offset a reduction in net tax revenue resulting
    from changes in law, regulation, or
    interpretation if, and to the extent that, the
    recipient government could not identify
    sufficient funds from sources other than the
    [ARPA funds] to offset the reduction in net
    tax revenue.
    86 Fed. Reg. at 26,807. Recognizing that “money is
    fungible,” the IFR states that even if ARPA funds “are not
    explicitly or directly used to cover the costs of changes that
    reduce net tax revenue, those funds may be used in a manner
    inconsistent with the statute by indirectly being used to
    substitute for” state funds that would “otherwise have been
    needed to cover” the reduction. Id. at 26,807.
    To identify direct or indirect offsets, the IFR provides
    state governments with a four-step framework. First, using
    the State’s “existing approach for measuring the effects of
    fiscal policies,” a State must “identify and value” any actions
    that it predicts will reduce tax revenue in a given reporting
    year. Id. at 26,809. Second, the State must “calculate the
    total value of all covered changes” to determine if there was
    STATE OF ARIZONA V. YELLEN                    11
    a reduction in net tax revenue. Id. If the reduction is below
    a de minimis level—1 percent of the reporting year’s
    baseline—the Offset Provision is not implicated. Id. Third,
    if a State’s annual tax revenue exceeds the amount received
    for fiscal year ending in 2019 adjusted for inflation, it is in a
    “safe harbor” and does not violate the Offset Provision. Id.
    If, however, there has been more than a de minimis reduction
    in net tax revenue from a change in state law, the fourth step
    is for the State to “identify any sources of funds” that have
    been used to offset the reduction.            Id. at 26,809.
    Macroeconomic growth, increases in revenue, and spending
    cuts in areas where the State has not spent ARPA funds can
    all be used to offset reductions in net tax revenue without
    violating the Offset Provision. See id. at 26,809. A State
    would be required only to repay any amount of federal funds
    from ARPA that was used to offset a reduction. Id. The IFR
    also outlines a detailed “Recoupment Process” that allows
    states to submit a request for reconsideration if the Treasury
    Department determines they violated the Offset Provision.
    Id. at 26,811–12.
    PROCEDURAL HISTORY
    Arizona sued the federal defendants in March 2021, soon
    after President Biden signed the Act into law, alleging that
    ARPA violates the Spending Clause and the Tenth
    Amendment. Specifically, Arizona alleges that ARPA’s
    Offset Provision is unconstitutionally ambiguous under the
    Spending Clause because the statute does not specify what it
    means to “indirectly offset a reduction in the [State’s] net tax
    revenue.” Arizona contends that the Offset Provision could
    be broadly interpreted as a “blanket prohibition forbidding
    States from cutting taxes in any manner whatsoever.”
    Second, the State contends that ARPA violates the Spending
    Clause by being unduly coercive and unconstitutionally
    12             STATE OF ARIZONA V. YELLEN
    commandeering its sovereign power to set its own tax policy
    in violation of the Tenth Amendment. In essence, Arizona
    contends that it was coerced into accepting the Offset
    Provision because of the size of the funds offered under
    ARPA and the fraught financial situation brought on by the
    pandemic.
    Arizona sought a preliminary injunction enjoining the
    federal defendants from recouping funds or otherwise
    enforcing the Offset Provision, as well as declaratory relief
    that the Offset Provision violates the Constitution. The
    district court dismissed the case for lack of subject matter
    jurisdiction, finding that Arizona did not demonstrate a
    cognizable injury in fact to establish standing.
    The district court rejected all five of Arizona’s
    arguments for standing. First, Arizona argued that it was
    injured by the Offset Provision’s ambiguity, which
    prevented it from understanding the limits placed on the
    federal funds. Reasoning that Congress met its duty under
    the Spending Clause by making the condition “explicitly
    obvious,” the district court rejected this theory. Second,
    Arizona argued that the Offset Provision’s ambiguity put
    Arizona policymakers in an unsettling position of
    uncertainty because they do not know how to avoid violating
    ARPA’s conditions. The district court found this argument
    unpersuasive because Arizona policymakers passed a $1.9
    billion tax cut, and Arizona did not offer evidence that their
    decision was at all affected by ARPA’s conditions. Third,
    Arizona claimed it was injured by the compliance costs
    imposed by the Treasury Department’s IFR. The district
    court rejected this theory because in ARPA, Congress vested
    the Secretary with the authority to order States to produce
    information, and the district court found these compliance
    costs to be “part and parcel” of ARPA. Fourth, Arizona
    STATE OF ARIZONA V. YELLEN                   13
    relied upon caselaw that recognizes standing for pre-
    enforcement challenges where there is a realistic danger of
    enforcement, arguing that here there is a realistic threat that
    the Offset Provision will be enforced. The district court
    disagreed, concluding that Arizona did not demonstrate a
    substantial likelihood that the condition would actually be
    enforced against it in the way Arizona fears. Finally,
    Arizona argued that it suffered an injury by being coerced
    into accepting the allegedly unconstitutional condition
    because of ARPA’s size and the pandemic-driven need for
    the ARPA funds. The district court rejected this final theory
    for standing, reasoning that Arizona would not lose any
    existing federal funding if it violated the Offset Provision
    and that Arizona did not allege facts showing it has
    undergone financial strain.
    Arizona’s suit is one of six nearly identical challenges to
    ARPA brought by various states, and in those cases the
    district courts have reached different conclusions on
    standing. Compare Ohio v. Yellen, 
    539 F. Supp. 3d 802
    ,
    813–17 (S.D. Ohio 2021), West Virginia v. U.S. Dep’t of
    Treasury, 
    2021 WL 2952863
    , at *6–7 (N.D. Ala. July 14,
    2021), Kentucky v. Yellen, 
    2021 WL 4394249
    , at *3 (E.D.
    Ky. Sept. 24, 2021), with Arizona v. Yellen, 
    2021 WL 3089103
    , at *2–5 (D. Ariz. July 22, 2021), Missouri v.
    Yellen, 
    538 F. Supp. 3d 906
    , 912–13 (E.D. Mo. 2021).
    Because Article III empowers this Court only to
    adjudicate “live cases or controversies,” we will not wade
    into disputes that would require us to “issue advisory
    opinions” or “declare rights in hypothetical cases.” Clark v.
    City of Seattle, 
    899 F.3d 802
    , 808 (9th Cir. 2018) (quotation
    marks omitted). Only the injury-in-fact requirement for
    standing is contested in this case. An injury in fact is “an
    invasion of a legally protected interest” that is “concrete and
    14             STATE OF ARIZONA V. YELLEN
    particularized,” and “actual or imminent, not conjectural or
    hypothetical.” Lujan v. Defenders of Wildlife, 
    504 U.S. 555
    ,
    560 (1992) (quotation marks omitted). A “concrete” injury
    is one that “actually exist[s],” meaning that it is “real, and
    not abstract.” Spokeo, Inc. v. Robins, 
    578 U.S. 330
    , 340
    (2016) (quotation marks omitted).
    Arizona’s arguments for standing fall under three
    primary theories. First, Arizona contends that it has standing
    because of the compliance costs imposed by the Treasury
    Department’s IFR. Second, Arizona relies upon caselaw
    permitting pre-enforcement challenges to statutes to support
    its argument that the future injury Arizona will suffer, if the
    Offset Provision is enforced against it, is sufficient to confer
    standing. Third, Arizona contends that the Offset Provision
    inflicts cognizable sovereign injuries upon the States by
    being unconstitutionally ambiguous and coercive. We
    consider each theory in turn, giving de novo review to issues
    of standing. Cal. Trucking Ass’n v. Bonta, 
    996 F.3d 644
    ,
    652 (9th Cir. 2021).
    DISCUSSION
    We first address Arizona’s compliance cost theory,
    which contends that the reporting requirements in the
    Treasury’s IFR establish an injury in fact by imposing a
    regulatory burden on the States. This theory fails for the
    simple reason that standing is measured at the time of the
    complaint. Lujan, 
    504 U.S. at
    569 n.4. When the complaint
    was filed, there was not a required compliance scheme. The
    compliance costs Arizona complains of come from the IFR,
    which was promulgated after Arizona filed its complaint.
    We agree with the district court that Arizona’s compliance
    cost theory should be rejected.
    I.
    STATE OF ARIZONA V. YELLEN                   15
    We next consider whether there is a “realistic danger of
    enforcement” giving rise to a cognizable injury for standing.
    Because Arizona accepted ARPA funds and then passed a
    tax cut, Arizona believes that there is a realistic danger that
    it will be required to return some of the ARPA funds it has
    accepted, which would amount to a concrete injury in fact.
    The district court rejected this theory, concluding that
    Arizona did not demonstrate a substantial likelihood that the
    condition would actually be enforced against it. Important
    to the district court’s analysis was that Arizona had not
    claimed to have “directly or indirectly” used ARPA funds to
    offset its tax cut, nor had Arizona claimed the tax cut it
    passed would result in a net tax revenue reduction triggering
    the Offset Provision. We have previously held a “likely ‘loss
    of funds promised under federal law’” satisfied Article III
    standing. City and Cnty. of San Francisco v. Trump, 
    897 F.3d 1225
    , 1236 (9th Cir. 2018) (quoting Organized Vill. of
    Kake v. U.S. Dep’t of Agric., 
    795 F.3d 956
    , 965 (9th Cir.
    2015)). We must here decide whether the potential future
    recoupment of federal funds under ARPA is similarly
    sufficient in this case to confer standing.
    Three factors must exist for a plaintiff to have standing
    to bring a pre-enforcement challenge to a law, as explained
    by the Supreme Court in Susan B. Anthony List v. Driehaus,
    
    573 U.S. 149
    , 159 (2014). The plaintiff must allege (1) an
    “intention to engage in a course of conduct arguably affected
    with a constitutional interest,” (2) “but proscribed by a
    statute,” and (3) there must be “a credible threat of
    prosecution” under the statute. 
    Id.
     (quoting Babbitt v. Farm
    Workers, 
    442 U.S. 289
    , 298 (1979)).
    The first Driehaus factor requires an intent to do an act
    “arguably affected” by a constitutional interest.
    Determining whether Arizona meets this factor to a degree
    16             STATE OF ARIZONA V. YELLEN
    resembles an invitation to reach the merits of Arizona’s
    constitutional claims. But the Supreme Court has cautioned
    that standing “in no way depends on the merits” and has
    instructed us to take as true all material allegations in the
    complaint and construe the complaint in favor of the
    plaintiff. Warth v. Seldin, 
    422 U.S. 490
    , 500 (1975).
    Viewing the Offset Provision through Arizona’s eyes, we
    must accept—for standing purposes—its allegations that the
    condition is unconstitutionally ambiguous and coercive. We
    conclude that the first Driehaus factor is met.
    In evaluating the second Driehaus factor, we must
    determine whether Arizona’s intended future conduct is
    proscribed by ARPA. To do so, we first examine what
    conduct is proscribed by the Offset Provision to evaluate
    whether Arizona’s desired course of conduct falls under the
    provision’s sweep. The Offset Provision is triggered by
    specific events. A State must first accept funds under ARPA
    and certify that it will meet ARPA’s conditions. Then, it
    must make a change to state law that results in a “reduction
    in net tax revenue.” 42 U.S.C 802(c)(2)(A). Finally, to
    violate the Offset Provision, the State must then use federal
    ARPA funds to “directly or indirectly” offset the reduction
    in net tax revenue. 
    Id.
     All these steps must be taken to
    trigger and violate the Offset Provision.
    Here, Arizona has accepted ARPA funds, certified that it
    will meet ARPA’s conditions, and passed a $1.9 billion tax
    cut. The district court rejected Arizona’s theory of standing
    under Driehaus because Arizona had not claimed that its tax
    cut will result in a reduction in its “net tax revenue,” nor
    claimed to have “directly or indirectly” used ARPA funds to
    offset the tax cut. On this point we diverge with the district
    court because its reasoning approximates requiring Arizona
    to admit to violating a law in order to have standing to
    STATE OF ARIZONA V. YELLEN                    17
    challenge it, a prerequisite the Supreme Court has repeatedly
    rejected. See Driehaus, 573 U.S. at 163 (2014) (“Nothing in
    this Court’s decisions requires a plaintiff who wishes to
    challenge the constitutionality of a law to confess that he will
    in fact violate that law.”); MedImmune, Inc. v. Genentech,
    Inc., 
    549 U.S. 118
    , 129 (2007); Free Enter. Fund. v. Pub.
    Co. Acct. Oversight Bd., 
    561 U.S. 477
    , 490 (2010).
    Presumably, a $1.9 billion tax cut will lead to a reduction in
    Arizona’s net tax revenue; it is hard for us to imagine how a
    tax cut of this magnitude would not. This means that
    Arizona has taken all requisite steps to violate the Offset
    Provision short of using ARPA funds “directly or indirectly”
    to offset a net revenue reduction from its tax cut. Unlike the
    district court, we do not require Arizona to explicitly confess
    to intended future conduct that is violative of the law it seeks
    to challenge.
    The concurrence suggests that Arizona “has alleged only
    an intention to pass a tax cut.” But Arizona has done more
    than announce an intention to pass a tax cut; it has passed
    one. The only thing Arizona has not yet done is allege an
    intention to use ARPA funds “directly or indirectly” to offset
    the resulting net revenue reduction from its tax cut. Because
    doing so amounts to a confession that Arizona will, in fact,
    violate the law, and the Supreme Court has instructed that
    plaintiffs need not do that, we disagree with the concurrence
    on this point.
    The third Driehaus factor, concerning whether there is a
    credible threat of enforcement, has dispositive weight in this
    case. We have developed a framework to evaluate whether
    a claimed threat of enforcement is genuine enough to confer
    standing. We consider (1) “whether the plaintiffs have
    articulated a ‘concrete plan’ to violate the law in question,”
    (2) “whether the prosecuting authorities have communicated
    18             STATE OF ARIZONA V. YELLEN
    a specific warning or threat to initiate proceedings,” and (3)
    “the history of past prosecution or enforcement under the
    challenged statute.” Thomas v. Anchorage Equal Rts.
    Comm’n, 
    220 F.3d 1134
    , 1139 (9th Cir. 2000) (citing San
    Diego Cnty. Gun Rts. Comm. v. Reno, 
    98 F.3d 1121
    , 1126–
    27 (9th Cir. 1996)). Where the challenged statute is new, as
    here, the history of past enforcement carries little, if any
    weight. Cal. Trucking, 996 F.3d at 652.
    A concrete plan need not be “cast in stone” but must be
    “more than a hypothetical intent to violate the law.”
    Thomas, 
    220 F.3d at 1139
    . The $1.9 billion tax cut Arizona
    passed is a sufficiently concrete plan in our view. As
    described above, we do not require Arizona to admit to
    violating the law or having a desire to do so.
    That the federal government has not disavowed
    enforcement of the Offset Provision is evidence of an intent
    to enforce it. Cal. Trucking, 996 F.3d at 653. And in this
    case, there is affirmative conduct by the Treasury
    Department evincing an intent to enforce the Offset
    Provision. In response to an inquiry from a group of
    Attorneys General, the Secretary of the Treasury wrote a
    letter confirming that the Offset Provision will be enforced
    (although, the Secretary said, not in the way feared by the
    States). In California Trucking, we recognized a sufficient
    intent to enforce a law where a state had “sent letters to
    businesses notifying them” of its interpretation of a new
    requirement under state law. 996 F.3d at 653. Like the
    letters in California Trucking, we view the Secretary’s letter
    as showing an intent to enforce the Offset Provision, albeit
    in a cooperative fashion inviting “ongoing dialogue”
    between the Treasury and the States. In addition to the
    Secretary’s letter, the Treasury’s IFR outlines the detailed
    and specific process that will be used to recoup funds from
    STATE OF ARIZONA V. YELLEN                  19
    States that violate the Offset Provision, giving more
    evidence of the government’s intent to enforce the
    challenged provision. 
    31 C.F.R. § 35.10
    . The concurrence
    suggests that this factor is not met because the Treasury has
    disavowed enforcing the law in the way Arizona fears. But
    the Secretary’s letter still affirms the Treasury’s intent to
    enforce the Offset Provision against the States, even if it
    clarifies that nothing in ARPA “prevents States from
    enacting a broad variety of tax cuts.” The Secretary’s letter
    and the recoupment process outlined in the IFR show the
    federal government’s intent to enforce the Offset Provision.
    Arizona has done everything short of confessing a desire
    to use ARPA funds “directly or indirectly” to offset the tax
    cut it passed. We disagree with the district court’s rejection
    of this theory of standing and hold that Arizona has alleged
    a sufficiently credible threat of enforcement to bring a pre-
    enforcement challenge to ARPA’s Offset Provision. There
    is a realistic danger that Arizona, after accepting federal
    funds under ARPA and passing a billion dollar tax cut, will
    be forced to repay federal funds for directly or indirectly
    using those funds to offset its tax cut, in violation of the
    Offset Provision. This feared future injury is sufficiently
    realistic and credible to confer standing under Driehaus and
    our caselaw describing its three-factor test.
    II.
    We examine Arizona’s sovereign injury theory of
    standing in the alternative. In our dual sovereign system,
    Arizona enjoys “special solicitude in our standing analysis.”
    Massachusetts v. EPA, 
    549 U.S. 497
    , 520 (2007). This
    special standing has relevance here, where Arizona alleges
    that ARPA infringes upon its sovereign rights. Specifically,
    Arizona argues that the Offset Provision’s ambiguity
    prevents Arizona from being able to exercise its choice
    20             STATE OF ARIZONA V. YELLEN
    voluntarily to accept ARPA funds and understand the
    consequences of agreeing to ARPA’s conditions. Arizona
    also contends that by coercing the States into accepting the
    Offset Provision, ARPA threatens Arizona’s sovereign
    prerogative to “tax its residents as it sees fit.”
    If we were reviewing these issues on a record replete
    with evidence submitted and a summary judgment ruling,
    and looking only for an issue of fact requiring trial, we might
    be somewhat skeptical of the degree to which Arizona is
    being coerced in derogation of its sovereign rights. But we
    do not review this today on appeal of a summary judgment
    ruling. We are reviewing only an order on a motion to
    dismiss which dismissed the complaint for lack of subject
    matter jurisdiction. As we have noted above, in this context
    we must take all allegations of the complaint as true. See
    supra Part I (citing Warth, 
    422 U.S. at 500
    ). We see no
    reason under normal juristic standards for us to dispute,
    deny, or discredit Arizona’s contention at this stage that
    ARPA and its Offset Provision specifically have a coercive
    impact on the State.
    We examine Arizona’s sovereign injury theory for
    standing through the lens of Spending Clause legislation
    being “in the nature of a contract.” Pennhurst State Sch. and
    Hosp. v. Halderman, 
    451 U.S. 1
    , 17 (1981). In Pennhurst, a
    class of residents at a Pennsylvania institution for people
    with disabilities challenged the conditions of their
    confinement, seeking closure of the institution. 
    Id.
     at 5–6.
    The plaintiffs relied upon a provision in a federal grant
    program calling for the “least restrictive” treatment setting
    to argue that this provision created a binding condition upon
    the States in how they used federal funds to treat people with
    disabilities. 
    Id. at 7
    . Rejecting that this provision created a
    STATE OF ARIZONA V. YELLEN                    21
    retroactive funding condition upon the States, the Court
    likened federal grants to contracts:
    [L]egislation enacted pursuant to the
    spending power is much in the nature of a
    contract: in return for federal funds, the States
    agree to comply with federally imposed
    conditions. The legitimacy of Congress'
    power to legislate under the spending power
    thus rests on whether the State voluntarily
    and knowingly accepts the terms of the
    “contract.” There can, of course, be no
    knowing acceptance if a State is unaware of
    the conditions or is unable to ascertain what
    is expected of it.
    
    Id. at 17
     (internal citations omitted).
    A few years later in South Dakota v. Dole, the Court
    articulated the outer bounds of Congress’s authority under
    the Spending Clause to attach conditions upon grants of
    federal funding. 
    483 U.S. 203
    , 207–08 (1987). One limit is
    that spending must be in pursuit of the “general welfare,” a
    broad and deferential term. 
    Id. at 207
    . A second limit is that
    “if Congress desires to condition the States' receipt of federal
    funds, it ‘must do so unambiguously . . . , enabl[ing] the
    States to exercise their choice knowingly, cognizant of the
    consequences of their participation.’” 
    Id.
     (alterations in
    original) (quoting Pennhurst, 
    451 U.S. at 17
    ). Third, any
    conditions should relate to the federal interest implicated by
    the spending. 
    Id.
     Fourth, conditions must not violate other
    constitutional provisions. Id. at 208. The Court further
    noted that “in some circumstances the financial inducement
    offered by Congress might be so coercive as to pass the point
    at which ‘pressure turns into compulsion.’” Id. at 211
    22                STATE OF ARIZONA V. YELLEN
    (quoting Steward Machine Co. v. Davis, 
    301 U.S. 548
    , 590
    (1937)).
    Arizona seizes upon several of these limitations to bring
    a facial challenge—or so we interpret—to ARPA’s Offset
    Provision. 1 To Arizona, the inherent limitations on
    Congress’s power to “lay and collect Taxes” and “provide
    for the . . . general Welfare of the United States,” U.S. Const.
    art. I, § 8, cl. 1, create constitutionally-imposed and
    enforceable criteria that “contractual” funding offers from
    the federal government must meet. When Congress does not
    meet one of these criteria, and say, extends a federal grant
    with ambiguous or coercive terms to the States, Arizona
    contends that this offer offends state sovereignty and gives
    rise to a cognizable injury in fact. We agree. We are mindful
    of the longstanding principle that federal courts “are without
    jurisdiction” to adjudicate “abstract questions of political
    power, of sovereignty.” Massachusetts v. Mellon, 
    262 U.S. 447
    , 484–85 (1923). But intangible harms can be concrete,
    Spokeo, 578 U.S. at 340, and here, Arizona has alleged
    sufficiently concrete and particularized harms to its ability
    to exercise its sovereign prerogatives, intangible as those
    prerogatives may be. Just as a contract can be challenged
    under state law for containing ambiguous terms or being a
    product of duress, so too do we think that the quasi-
    contractual funding offer at issue here can be challenged by
    Arizona at the outset for offering conditions that are
    unconstitutionally ambiguous or coercive. States have
    standing when an allegedly unconstitutional funding offer is
    made to them, and they do not need to first violate a
    1
    Whether Arizona’s Spending Challenge is facial or as applied was
    not briefed by the parties, and we suggest that they brief this issue before
    the district court.
    STATE OF ARIZONA V. YELLEN                   23
    condition of an allegedly unconstitutional contract to have
    standing to challenge it.
    In rejecting Arizona’s theory of injury based upon
    having a right to an unambiguous funding offer from the
    federal government, the district court concluded that the
    Spending Clause requires Congress to be unambiguous
    about the existence of a condition, not what the condition
    requires. Whether or not the district court is correct that
    Congress “fulfilled its duty” in making the existence of the
    Offset Provision known, this analysis examines whether the
    condition is ambiguous, and not whether being offered
    ambiguous terms is a cognizable injury. Similarly, in
    rejecting Arizona’s theory of injury based upon being
    coerced into accepting the Offset Provision, the district court
    pointed to Arizona’s delay in accepting funds and the lack of
    evidence of any financial strain to conclude there was not
    standing. This analysis, however, evaluates the merits of
    whether ARPA is coercive instead of evaluating whether
    being coerced is a cognizable injury. A district court should
    be cautious not to confuse perceived “weakness on the
    merits with absence of Article III standing.” Ariz. State
    Legislature v. Ariz. Indep. Redistricting Comm’n, 
    576 U.S. 787
    , 800 (2015) (quoting Davis v. United States, 
    564 U.S. 229
    , 249 n.10 (2011)).
    At this early juncture, we must take Arizona’s
    allegations to be true. See Warth, 
    422 U.S. at
    499–502. The
    federal government and the district court discredit Arizona’s
    interpretation of the Offset Provision, but differences in what
    the Offset Provision means and how it may be enforced go
    to the merits of Arizona’s claims, and not to whether a court
    has jurisdiction to hear these claims. See Cath. League for
    Religious & C.R. v. City & Cnty. of San Francisco, 
    624 F.3d 1043
    , 1049 (9th Cir. 2010) (en banc); City and Cnty. of San
    24                STATE OF ARIZONA V. YELLEN
    Francisco v. Trump, 
    897 F.3d 1225
    , 1236 (9th Cir. 2018).
    In City and County of San Francisco v. Trump, the parties
    “disputed the scope of the challenged measure,” but we held
    it was enough for standing purposes that if the plaintiff’s
    interpretation of the statute was correct, it would “suffer
    serious consequences.” 897 F.3d at 1236. Here, Arizona has
    demonstrated that if the Offset Provision is as ambiguous
    and coercive as it alleges, it will face serious consequences
    in losing control over its taxing policies and being held to a
    funding offer that it does not understand. Whether there is
    merit to these feared consequences is a separate matter, but
    for today, we hold that the district court erred in dismissing
    Arizona’s claim for lack of subject matter jurisdiction.
    III.
    Concluding that Arizona has standing to bring its
    challenge to ARPA, both on its theory of realistic danger of
    enforcement, and alternatively, on its theory of injury to
    sovereign rights, we decline to turn to the merits of
    Arizona’s constitutional claims. We think it is a better
    procedure to have the district court make a ruling on the
    merits in the first instance, as the district court’s views can
    only help our court to resolve the difficult issues presented. 2
    We reverse the district court’s ruling on standing and
    conclude that the district court has subject matter jurisdiction
    to hear this case. We remand for the district court to consider
    the merits of Arizona’s Spending Clause and Tenth
    Amendment claims.
    2
    We also note that, after we heard argument in this case, the
    Treasury Department published a final rule implementing ARPA and the
    Offset Provision. Coronavirus State and Local Fiscal Recovery Funds,
    
    87 Fed. Reg. 4,338
     (Jan. 27, 2022). In considering the merits, the district
    court also will have the benefit of that final rule implementing ARPA.
    STATE OF ARIZONA V. YELLEN                  25
    CONCLUSION
    Because standing “in no way depends on the merits,”
    Warth, 
    422 U.S. at 500
    , our decision today should not be
    construed as commenting in any way on the merits of
    Arizona’s case. We limit our decision to the narrow issue of
    standing and hold that the district court has subject matter
    jurisdiction to hear this challenge to ARPA.
    REVERSED AND REMANDED.
    R. NELSON, Circuit Judge, concurring:
    I agree that Arizona has standing to challenge the Offset
    Provision on its theory of sovereign injury and concur in
    Section II of the majority’s opinion.
    I disagree, however, with the majority’s conclusion that
    Arizona has alleged “an intention to engage in a course of
    conduct arguably affected with a constitutional interest, but
    proscribed by a statute.” See Susan B. Anthony List v.
    Driehaus, 
    573 U.S. 149
    , 159 (2014) (quoting Babbitt v.
    Farm Workers, 
    442 U.S. 289
    , 298 (1979)). Arizona never
    alleged that it has taken (or would take, if not for fear of
    enforcement) action proscribed by the Offset Provision. The
    lack of such an allegation dooms Arizona’s argument for
    standing on this basis.
    Article III of the Constitution limits our jurisdiction to
    “Cases” and “Controversies.” U.S. Const., art. III, § 2. “The
    doctrine of standing gives meaning to these constitutional
    limits by ‘identify[ing] those disputes which are
    appropriately resolved through the judicial process.’”
    Driehaus, 573 U.S. at 157 (alteration in original) (quoting
    26             STATE OF ARIZONA V. YELLEN
    Lujan v. Defenders of Wildlife, 
    504 U.S. 555
    , 560 (1992)).
    “To establish Article III standing, a plaintiff must show
    (1) an ‘injury in fact,’ (2) a sufficient ‘causal connection
    between the injury and the conduct complained of,’ and (3) a
    ‘likel[ihood]’ that the injury ‘will be redressed by a
    favorable decision.’” 
    Id.
     at 157–58 (alteration in original)
    (quoting Lujan, 
    504 U.S. at
    560–61). Generally, the injury-
    in-fact requirement is satisfied by an injury that has already
    occurred.      But we also recognize that threatened
    enforcement of a law can create an injury in fact. Id. at 158.
    In those circumstances, we may consider pre-enforcement
    challenges “under circumstances that render the threatened
    enforcement sufficiently imminent.” Id. at 159. A mere
    possibility of future enforcement will not do; the likelihood
    of future enforcement must be “substantial.” California v.
    Texas, 
    141 S. Ct. 2104
    , 2114 (2021) (quoting Driehaus, 573
    U.S. at 164); see also Massachusetts v. Mellon, 
    262 U.S. 447
    , 488 (1923) (“The party who invokes the power [of
    Article III courts] must be able to show, not only that the
    statute is invalid, but that he has sustained or is immediately
    in danger of sustaining some direct injury as the result of its
    enforcement . . . .”).
    Likelihood of enforcement is substantial when a plaintiff
    alleges (1) “an intention to engage in a course of conduct
    arguably affected with a constitutional interest,” (2) “but
    proscribed by a statute,” and (3) “there exists a credible
    threat of prosecution thereunder.” Driehaus, 573 U.S. at 159
    (quoting Babbitt, 
    442 U.S. at 298
    ). In Driehaus, for
    example, two advocacy organizations challenged an Ohio
    statute prohibiting “false statements” in political campaigns.
    Id. at 151. The law allowed any person with knowledge of
    a purported violation to file a complaint with the State. Id.
    at 164. One organization had already been subject to
    enforcement proceedings, initiated after a candidate filed a
    STATE OF ARIZONA V. YELLEN                   27
    complaint about the organization’s attempts to display a
    billboard stating that the candidate “voted FOR taxpayer-
    funded abortion.” Id. at 154. After losing the election, the
    candidate moved to withdraw his complaint. The plaintiff
    organizations challenged the state law, alleging that they
    “intend[ed] to engage in substantially similar activity in the
    future” and “face[d] the prospect of [their] speech and
    associational rights again being chilled” by future
    complaints. Id. at 155 (second alteration in original).
    The Supreme Court held that the organizations had
    standing to bring a pre-enforcement action.                The
    organizations alleged “specific statements they intend[ed] to
    make in future election cycles” that would be prohibited. Id.
    at 161. The text of the statute covered the plaintiffs’
    intended speech (“concerning the voting record of a
    candidate,” id. at 152), and the statute had been enforced
    against one of the plaintiffs, id. at 162. The Court did not
    require plaintiffs “to confess that [they] will in fact violate
    th[e] law” and held that the organizations had established
    that their intended future conduct would be proscribed by the
    statute because it would subject them to future enforcement
    proceedings. Id. at 163.
    The Court held that the final requirement—a substantial
    threat of future enforcement—was satisfied for three
    reasons. First, there was a history of past enforcement
    because one organization had been the subject of prior
    enforcement proceedings. Id. at 164. Second, the credibility
    of the threat was bolstered by the fact that any person could
    file a complaint. Id. Because “the universe of potential
    complainants [was] not restricted to state officials who
    [were] constrained by explicit guidelines or ethical
    obligations,” there was a substantial risk of complaints from
    a multitude of parties, including political opponents. Id.
    28             STATE OF ARIZONA V. YELLEN
    Finally, the Court noted that enforcement proceedings were
    frequent and the commission “ha[d] not disavowed
    enforcement if petitioners make similar statements in the
    future.” Id. at 165.
    We have followed a similar approach in this Circuit. In
    Real v. City of Long Beach, we held that a plaintiff had
    standing to challenge a city’s zoning ordinance when he
    alleged an intent to open a tattoo shop without the required
    permit. 
    852 F.3d 929
    , 934–35 (9th Cir. 2017). Like the
    advocacy organizations in Driehaus, the plaintiff in Real had
    alleged a specific intent to engage in conduct proscribed by
    the challenged ordinance. 
    Id.
     And, as in Driehaus,
    enforcement proceedings had happened in the past (albeit
    against non-plaintiffs). 
    Id.
     The City vigorously enforced its
    zoning ordinances and told the plaintiff that he would be
    subject to enforcement proceedings. 
    Id.
     The plaintiff had
    standing to challenge the ordinance because it appeared
    “likely that the City would take action against [him] if he
    opened a tattoo shop.” Id. at 935.
    More recently, we held that a trucking trade association
    had standing to challenge a new California law that codified
    a test for classifying workers as either employees or
    independent contractors. Cal. Trucking Ass’n v. Bonta, 
    996 F.3d 644
    , 649 (9th Cir. 2021). The trade association
    established a “concrete plan” to violate the law by alleging
    that its members actively maintained policies that were “in
    conflict with” California law. Id. at 653. The association
    also established a substantial likelihood of enforcement
    proceedings because the state had refused “to disavow
    enforcement” against association members and declared its
    “intention to enforce” the new law. Id. Because the law was
    relatively new, we noted that the history of enforcement
    carried “little weight.” Id. Even so, the State had done more
    STATE OF ARIZONA V. YELLEN                   29
    than declare its intentions; it had sent letters to businesses
    notifying them that they were subject to the law and had
    commenced several prosecutions against businesses for
    violating the law. Id.
    On the other hand, we found standing lacking in cases
    like Safer Chemicals, Healthy Families v. EPA, 
    943 F.3d 397
     (9th Cir. 2019). In Safer Chemicals, we held that
    plaintiffs challenging agency rules do not have standing
    when “it is not even clear what [agency] procedures will be,
    let alone whether [the agency] will employ them in a way
    that injures” the plaintiffs. Id. at 415. Ambiguity in the
    challenged provisions hindered our ability to “predict
    whether [plaintiffs] will be harmed in the way they claim, or
    whether the [government] will in fact apply the[] rules as
    [plaintiffs] wish.” Id. We explained that plaintiffs might
    have standing in the future, if the agency enforced the rule
    in the way feared by plaintiffs. Id. But we declined to make
    assumptions about how the government would enforce an
    ambiguous provision to create standing based on the
    plaintiffs’ allegations. Id.
    There are striking differences between the allegations in
    this case and the allegations in cases finding pre-
    enforcement standing. The Offset Provision prohibits states
    from using American Rescue Plan Act (ARPA) funds “to
    either directly or indirectly offset a reduction in the net tax
    revenue.” 
    42 U.S.C. § 802
    (c)(2)(A). Arizona alleged only
    an intention to pass a tax cut (which it has now passed). It
    did not allege a reduction in net tax revenue, nor did it make
    any allegation about how a potential post-tax-cut budget
    would be structured. Unlike the large number of potential
    complainants in Driehaus, the universe of potential
    complainants in this case is limited to “officials . . .
    constrained by explicit guidelines or ethical obligations.”
    30             STATE OF ARIZONA V. YELLEN
    See 573 U.S. at 164. And unlike the frequent past
    proceedings in Driehaus and Real, Treasury officials have
    never initiated enforcement proceedings under the Offset
    Provision. Indeed, Treasury has explicitly disavowed any
    prohibition against states enacting tax cuts. See Real, 852
    F.3d at 934–35; cf. Lopez v. Candaele, 
    630 F.3d 775
    , 788
    (9th Cir. 2010) (“[C]laims of future harm lack credibility
    when . . . the enforcing authority has disavowed the
    applicability of the challenged law to the plaintiffs.”).
    Arizona’s pleadings leave us to make a series of factual
    and legal leaps to establish (1) an intention to engage in a
    course of conduct arguably affected with a constitutional
    interest, (2) but proscribed by the Offset Provision, and (3) a
    credible threat of prosecution thereunder. See Driehaus, 573
    U.S. at 159. Nowhere in its complaint does Arizona allege
    that it has (or plans to) directly or indirectly offset a
    reduction in net tax revenue. For Arizona to have standing
    under Driehaus, we must infer that the contemplated tax cut
    will not be offset by macroeconomic growth or cuts in
    spending not affected by ARPA. Then we must infer that
    Treasury will enforce the Offset Provision in a way that it
    has explicitly disavowed and never threatened. Inventing
    standing with such assumptions is inconsistent with
    precedent.
    A tax cut, on its own, does not fall within the Offset
    Provision’s ambit. Without more, we cannot infer both (1) a
    reduction in net tax revenue and (2) conduct that might count
    as an “offset.” Had Arizona alleged an intent to offset a
    reduction in net tax revenue in some specific way, it may
    have separately established standing under its pre-
    enforcement theory. But as things stand, the specter of
    enforcement is too hypothetical to present a “Case” or
    “Controversy” for our review.
